A 9.5 tonnes capacity of ammonia refrigerator operates between evaporator and condenser temperature of -13°C and 28°C is needed in a food storage locker. The refrigerant is sub-cooled by 4°C before entering the expansion valve. The vapour is 0.90 dry as it leaves the evaporator coil. The compression in the compressor is adiabatic type.
